EJEECIPICATIOEQ forming part of LettersPatent No. 311,818, datedFebruary 3, 1885.

Application tiled May 15, 1884. (No model.)

To all whom, it may concern.-

Be it known that we, EDWARD Z. OOLLTNGS, residing at Camden, in thecounty of Camden and State of New Jersey, and CHARLES F.

PIKE, residing at Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, citizens of the United States, have invented certainnew and useful Improvements in Re frigerators, of which the following isa speci- IO fication, reference being had therein to the accompanyingdrawings, wherein- Figure l is a longitudinal vertical section of arefrigerator embodying our improvements. Fig. 2 is a broken elevationillustrating a modification, and Figs. 3 and'et are detail sections ofmodified forms of pans or troughs for the refrigerator.

Our invention has relation to that form of refrigerator provided with anice-box and a series of pans or troughs for conducting the drip from theice-box through and out of the refrigerator, and it has for its objectto increase the efficiency of the drip, or cause it to produce greaterrefrigerant results.

Our invention accordingly consists of the combination, construction, andarrangement of parts, as hereinafter described and claimed.

In the drawings, A represents a refrigerator-box, which may be portableor stationary 0 and of any suitable construction and configuration. Itis provided with a lid, a, and an ice-box, a, having a drip-outlet, a".

B B represent a series of pans of any construction in cross section.They may be of 5 uneven lengths, as shown, increasing from abovedownwardly, or they may all be of the same size, and are seen red inposition in any suitable manner. Each pan is provided with a siphonoutlet or pipe, I), which may be a 40 bent pipe, as indicated in Fig. 1,or formed as represented .in Figs. 3 and 4. The pans or troughs B may belongitudinally parallel or inclined, as shown in Fig. 4.

The operation is obvious. The drip from 5 ice-box a falls into the firstpan of the series B, and accumulates therein until its level rises aboveand forces the air from or creates avacuum in bent pipe I), to start itsiphoning.

Such drip is then siphoned from said first pan into the succeeding pan,and this, being larger than the former, detains the drip therein untiladditional drip is supplied thereto to start the siphonage. As soon asthis takes place the drip in the second pan passes into the third pan,and so on until it finds its exit from. box A. The drip, it will benoted, is detained in each pan for a certain length of time, so that itspassage or flow through box A is slow or intermittent, and the fullbenefit of its reduced temperature is obtained, as much as it ispossible to do so, to effect the. best refrigerant results in box A.

Instead of using fixed pans and siphon outlets or pipes, as abovedescribed, the latter may be dispensed with and the pans pivoted, asindicated in Fig. 2, so that when a given quantity or volume of wateraccumulates therein they will tilt upon their pivotal points and emptythemselves and return to their normal position by gravity or under theinfluence of a spring.

While we have shown and described tWO forms of pans for effecting anintermittent flow of drip through the refrigerator-box A, yet we do notwish to be understood as limiting ourselves thereto, as it is obviousthat the construction, arrangement of the pans, and the operation ofemptying them to produce the intermittent fiow may be varied Withoutdeparting from the spirit of our invention. It 9-0 will be noticed thatthe drip from the ice-box is continuous as long as the latter issupplied with ice, and that the flow of the drip is intermittent throughthe pans B.

Instead of using drip from the ice in box a, it may be filled with orhave a supply of refrigerant liquid.

What we claim is 1. A refrigerator having an ice-box providedwith a dripoutlet and a series of pans or troughs communicating with one another,and providing an intermittent passage or flow for the drip,substantially as shown and described.

2. A refrigerator having an icebox with dripoutlet and a series of pansor troughs which successively receive the drip and au toinatically andintermittently discharge it, substantially as shown and described.

3-. A refrigerator having an ice box with drip-outlet and a series ofcommunicating pans or troughs adapted to receive and detain the drip.therein and automatically and inter- I mittentlydischarge'it therefrom,substantially as shown and described.

4. A refrigerator having an ice bOX- with. drip-outlet and a series ofcommunicating pans or troughs of gradually-increasing size, adapted toreceive, detain, and automatically and intermittently discharge thedrip, substantially as shown and described.

5. A refrigerator provided with a supply of refrigerant liquid or drip,and a series of communicating pans or troughs adapted to receive anddetain such liquid therein and automatically and intermittentlydischarge it therefrom, substantially as shown and described. v 6.. Themethod herein described for producing the refrigerant results inrefrigerators, which consists of passing an intermittent flow ofrefrigerant liquid through the refrigerator, substantialy as shown anddescribed.

7. A refrigerator having an ice box with drip-outlet and a seriesof pansor troughs having siphon outlets which intermittently draw the waterfrom the pans, substantially as shown and described.

8. A refrigerator having iceboX a, dripoutlet a", and pans B, ofdifferent sizes, and
